I've read comments from posters on other forums that the crystals that are used in personal cooling systems (neckkerchiefs, vests, etc) release some sort of toxic substance when wet that can be absorbed into the skin. The items are intended to be wetted and worn next to the skin, so it would be important to know if this was likely. No one has presented a shred of evidence, just saying that they heard or read somewhere that one should be careful in using it. I tried a google search but came up with so much information that didn't apply that I hoped someone here could at least point me in a direction to get further information.
